This project describes the design and construction of an Automatic Voltage Regulator (AVR) and an Electronic Load Controller (ELC) for the voltage and the frequency regulation in an island Micro-hydropower Plant (MHP). For the frequency control, the speed regulation by ballast load method has been used. To this approach, a combined binary-continuous load regulation was employed. The implemented AVR...
A new method to reduce 120Hz output voltage ripple of LLC resonant converter using resonant controller is proposed in this paper. In the proposed control method, the resonant controller can give very high gain at this frequency, so it can reduce 120Hz output voltage ripple significantly. Employing the resonant controller in software, along with the conventional PI controller, the proposed technique...
